Description
Technical field
The present invention relates to a kind of preparation method of PVDF fluorocarbon powder paints.
Background technology
Fluorocarbon coating, as a kind of high performance coating products, is with fluorine resin as main film forming matter, and in fluororesin
On the basis of through a kind of new coating material for being modified, processing.Fluorocarbon coating is mainly characterized by resin containing a large amount of
F-C keys, bond energy is 485kJ/mol, the bond energy (413kJ/mol) far above C-H.Therefore in illumination, thermal environment or extensive chemical
Under corrosive environment, F-C keys are maintained to stable state, so as to show the weatherability of fluorocarbon coating overlength, protrusion
, used as a kind of emerging high weatherability coating, fluorocarbon coating was come out in 20th century for salt fog resistance and resistant to chemical media corrosion stability
The fifties, the anticorrosion engineering of heavy construction steel construction, the such as steel construction of stadiums, large bridge have been widely used in it
Heavy anti-corrosion paint etc..
At present, the application form of domestic fluorocarbon coating is mainly based on solvent based coating, the production of solvent-borne type fluorocarbon coating and
Construction technology is ripe, coating it is numerous it is architectural embodied very well, traction is high.With country to environmental protection increasingly
Pay attention to, using being increasingly subject to limit, coating reduces VOC emission amount as far as possible and weighs very much solvent-borne type fluorocarbon coating in first application
Will.Powdery paints VOC emission amount is very low to be more suitable for using in high-temperature baking type occasion.
Fluorocarbon powder resin kind is a lot, but it is little to apply to the kind of powdery paints.Consider from practical application angle,
Thermoplasticity and thermosetting 2 kind can be divided into by film forming matter as building material surface fluorocarbon powder resin.Thermoplastic fluoroelastomer carbon dust is applied
Material is with PVDF resins as base-material；Thermosetting fluorocarbon powder coatings are with CTFE-vinyl ethers/ester resin as base-material.
PVDF fluorocarbon powder paints occur in 20 century 70s, and FEVE fluorocarbon powder paints were opened from late 1990s
Beginning is commercially applied, and existing market occupation rate is still very low.In recent years, domestic powdery paints industry is needed to fluorocarbon powder paint
Ask more and more vigorous；External Middle East is many, and building requirement coating is without solvent and weatherability will reach AAMA2605-
2005 standards, increase to fluorocarbon powder paint demand；Asia and Oceania area have equally to fluorocarbon powder paint demand
Tendency, these market development directions are fast-developing there is provided strong impetus in building materials field to fluorocarbon powder paint.
PVDF is polyvinylidene fluoride, and PVDF fluorocarbon coatings are the top products in metal current building coats, with
Confirmed most permanent weather resistance, and with excellent resist chemical performance and excellent mechanical performance, it is nearly all
Advanced metal building all use is all fluororine-carbon coating.
But, current PVDF thermoplastic fluoroelastomers carbon coating almost all is, using solvent-borne type PVDF F-C paints, to need in solution
Middle dispensing formulations raw material.Therefore inevitably in the feed, production process and contain solvent using process.With country
Pay attention to day by day to environmental protection, due to its VOC emission problem,, using being increasingly subject to limit, coating is first for which for solvent-borne type fluorocarbon coating
Reduce VOC emission amount during secondary application as far as possible extremely important.
And some adopt aqueous PVDF thermoplastic fluoroelastomers carbon coating dispensing formulations raw material in water-based emulsion (or aqueous solution), though
So relatively above-mentioned solvent-borne type fluorocarbon coating reduces by 70% or so solvent, but still in the feed, production process and use
Process contains solvent.
Existing PVDF fluorocarbon powder paints several method shortcoming：Spray drying process, melting extrusion mixing method, and front road
Technique spray drying process postchannel process adopts melting extrusion mixing method.
1st, spray drying process：PVDF thermoplasticity F-C paints are first prepared, then PVDF fluorine carbon dusts are prepared using drying process with atomizing
Last coating.In manufacture process, in its raw material, there is solvent, production process has solvent, this technique is loaded down with trivial details, high energy consumption, also there is solvent
A series of problems, such as recycling.
2nd, melting extrusion mixing method：PVDF resins, acrylic resin, pigment, auxiliary agent, filler are adopted for raw material → high-speed stirring
Mix type mixer premixing → double screw extruder extrusion → cooling it is broken → liquid nitrogen deep is broken → classification sieves → PVDF fluorine
Fluoropolymer Powder Coatings finished product.It is poor to there is melting extrusion melting effect in this method, and extruder screw not easy cleaning, later stage also need to hold high
Expensive loaded down with trivial details liquid nitrogen frozen disintegrating process, industrial applications difficulty are larger, and domestic also no producer is produced using the method at present
PVDF fluorocarbon powder paints, no product releases market, only document introduction to this method so far.
3rd, the postchannel process of the front road technique+melting extrusion mixing method of spray drying process first prepares PVDF thermoplasticity F-C paints
→ vacuum is not exclusively drained solvent → will be pressed into sheet → just crush → drain solvent → liquid nitrogen deep into thing and crush → was classified
Sieve → PVDF fluorocarbon powder paint finished products.So far no product releases market, only document introduction to this method page.
Above-mentioned 2,3 two methods only have document introduction at present, it is impossible to volume production, trace it to its cause：Lack substantial production hand
Section, the process costs for not having perfect process facility, costliness loaded down with trivial details etc..And production process still uses solvent, inevitably
Still there is VOC emission.
